摘要: Methods and apparatus for efficient purging from an imaging hood are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms.

摘要: Visual electrode ablation systems are described herein which include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An electric current may be passed through the fluid such that it passes directly to the tissue region being imaged and the electrical energy is conducted through the fluid without the need for a separate ablation probe or instrument to ablate the tissue being viewed.

摘要: Systems and methods for unobstructed, visualization and ablation, particularly of the pulmonary veins, are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration as well as one or more expandable anchors which are temporarily securable within a respective pulmonary vein while allowing blood flow to pass through the anchor unimpeded. With the one or more non-impeding anchors secured within a respective pulmonary vein, ablation of the tissue surrounding the ostium or several ostia may be effected with the catheter while the tissue is under direct visualization.

摘要: Axial visualization systems which utilize axially aligned imaging instruments for visualizing through an imaging hood purged of blood via a transparent fluid are described where an imaging element extending from a support shaft may be aligned within a working lumen defined through a deployment catheter. The imaging element may be positioned distal to the hood in its collapsed state and within the hood in its expanded state. The imaging element may be configured to seat itself securely within the catheter or to angle itself to adjust the viewing angle. Additionally, a disposable visualization sheath having a transparent lens may also be utilized to house an imaging instrument therein.
